That is about what I have. When this kid gets outside forget about it. They have 1 decent shot at his flag and if they miss he is gone. I get what @Bengal B is saying though and I can't let this turn into the DJ show. So he will play other spots and I will mix in some other kids and when we need a TD I will give him the ball.
Just let it be the DJ show until you have a comfortable enough lead to let everyone else get the ball.
At most levels, yes. But in Pee wee football, the most important thing is teaching them how to play football and to have fun. It's not all about the quarterback and not everybody can be the quarterback. There are not a lot of exceptional athletes nor big bodies yet and playing them at every position prepares them better for specializing later on. A son of a former girlfriend of mine played Pee wee and all he wanted to do was play quarterback. But the coach made him play defense and lineman and kicker, too, and he was annoyed by it but ended up discovering that he was a very good receiver and that is what he played in high school. If a young Leonard Fournette is allow to come in, do it all himself, and dominate everybody then nobody else is having any fun or learning any football and they leave. It's why Fournette had to leave Pee Wee ball. It became a "he goes or everybody quits" situation. Shane needs to play the superior athlete and try to win the game. But he must also play others and make the athlete block and tackle, too.
How soon before DJ demands to be traded? You have to create your own process and stick to it. The kids don't have to like you but they must respect you and that your decisions are in the best interests of the team. I have to agree with @LaSalleAve to let DJ get you a comfortable lead and then let the other kids have at it. Take it from a coach with a lifetime undefeated record. I was quarterback and coach of a flag team when I was 18 that was undefeated and unscored upon city BREC league champion.
So are successful head coaches. Winning isn't everything, It's the only thing - Vince Lombardi You off all people, with your military experience should be able to instill a discipline in those kids that their coddling, enabling parents have failed to do. Learning the value of teamwork to achieve the common goal can be as rewarding to the young as to anybody. Especially if you take them out for pizza and ice cream after a win.
